Application filed June 1,

present in use and will permit of the warping frame and the creel being placed more` closely together than at present, thus lessen- `ing the length of yarn between the unwinding point and the point where the yarn is wound upon the beam. The invention relates particularly to creels for the reception of warp cops, cheeses, or any other form in which yarn is wound, hereinafter for convenience referred to as a cop, but is also applicable for use with flanged warpersl bobbins.

In carrying theinvention into effect lprovide a half cylinder which comprises the creel proper, this half cylinder having mounted on its inner face spindles adapted to receive the cops to be wound rupon the beam. A comb is fitted parallel to and in the plane of the longitudinal axis of the halt cylinder, and all the yarns from the cops are led through the teeth of this comb and thence to the beaming frame. It follows from this construction that the length of yarn from each cop is the same another' the cops are unwound in a direction parallel to their longitudinal axis, and equal tension of the yarn throughout the beaming operation, with a minimum of resistance to unwinding of the yarn from the cops, is obtained. f

The invention will be fully described with reference to the accompanying` drawings. wherein Figure l is a diagrammatic view in side elevation of a creel constructed accordiag` to my invention. y

arrangement in staggered relationy of rows of cop-carrying spindles, and

llfigure 5 is a detail of yarnguiding means. ln Figures l and 2, it will be seen that in principle the .creel is comprised of a support lof semi-cylindrical form, which support may be of kany convenientmaterial, such Las wood, sheet metal, etc., arranged in relation to the floor in such a manner that its kaxis be parallel thereto, that is to say, horizontal, the sideQ nearest thefwarping frame being below the level. of the axis, and,`

the side being on the contrary above the level of said axis. The'position of the half* cylinder l may be maintained in any convenient manner as for instancefby the feet 4. On the inner face of the part l arear.- ranged in any convenient manner, preferably in staggered rows as shown in Figure 4, short spindles 5, .the axis of which coincide with radii Vof the `half cylinder l, these spindles being secured on the innercurved face of the part l in any convenient manner. They may or may not be spring mounted thereon. Theirpurpose is to receive the cops 6 of which the yarns 7, being unwound in a direction parallel to the axis ofthe cop, form the fleece of yarns 8 to be warped, this fleece 8 passing between the comb of the creeland the first tension bar 9 of the warping frame which lattermay be. of any convenient type which ensures a highspeed of warping.

The comb of the warping frame is arranged in a manner to be approximately on the longitudinal axis ofthe half cylinder which forms the support l withits spindles 5. It is therefore approximately y at an equal 'distance between the two extreme ends 2 and 3 of the part l, andthus equidistant from any pointof kthe inner surface of the cylindrical part l. The comb is provided with dents l() fitted vertically on its upper edge, the body l1 thereof being preferably circular in section, to lessen friction between itself and the yarns 7 which pass over it from the cops 5 and through the dent-s 10 to form, after their passage though the said dents, the fleece 8 to be wound on the beam.

The comb may be mounted at the centre of the half cylinder in any appropriate manner, as for instance by end supports l2 fixed to the inner face of the half cylinder l, with intermediary supports if desired.

Byvthese arrangements and the charactei-istie combination vof the elements of a Creel it will be noted that: (a) the greater part of the length of the fleece of yarns 8 occupies a space above the 'surface 'occupied by the creel itself, which permits of the placing of the warping frame nearer to the Creel, thus saving space. (b) The length of the yarns 7, between the point where they leave their respective cops 6 and where they enter the dents of the comb 1l, is practically always equal for all the yarns being unwound, thus ensuring` aconstant and uniform tension 'on all the yarns throughout the unwinding operation. This allows of warping at a high speed, the total length of the yarns 7-8 bein-g practically the same :trom each cop up to the point of winding on the beam. (c) The axes oi' each of the cops 6 mounted on their spindles 5, being situated on radii of the cylinder l are prolonged into the axis of the said halt cylinderg'thus the yarns 7, unwinding practically on a line parallel with the 4said radii, present the minimum of re sistance to unwinding, the result being a great decrease kin the proportion of broken yarn ends. The side y2 being belowthe level oi the cylinder axis, and thus below the comb l'0ll, the fleece of yarns S is a little inclined thus allowing the. warper vto tie up broken ends easily.

Following the principle otl the invention, as shown diagrammatically in the-'Figures l and '2, a detailed method of carrying it out is given `in Figure 3, according to which it will be seen that the hali' cylinder l is mounted in a Yform of casing 13, and that the cops 6 may be grouped together in twos or threes, or in greater numbers, around bars 14 the axes of which are, like those of the spindles 5, coincident with radii of the halt cylinder l.. The bars ll each carry at their `ends the cross bars l5, each supporting two, three or more yarn guides 1G, through which' the yarn from the cops 6, still maintaining their line parallel with radii ot the half cylinder, pass towards the comb ILO-l1 to form the iieece 8 to be warped.

These yarn guides 16 serve to obviate an excess ot' ballooning of the yarns 7, aslight resistance to the unwindng of the bobbins being set up by the yarn 7 from each cop being wound once around the bar l5 as shown in Figure 5. y

lt will be understood that, for the practical carrying out of the invention, changes, modiitications and improvements in the details may be mace, in the type of spindles used, in the torm ot' the cops 6, oi the yarn guides ielf-l-cl; o'V the support l2 ot' the comb itl-ll; and oi the comb itself, as well in the nature, dimensions. and method of construction oi? the support i., without departing 'troni tire principle of the said invention.

For example, 'the central comb lO-ll. might be replaced by a bar bearing yarn guides, with or without a stop motion.

ln certain cases the invention may be applied to the warping otl bobbins flanged warpers bobbins, braking means being pro vided, in this case, for each end ot yarn.

llhat l' claim, is:

l. A creel tor the reception of warp cops and other forms of wound yarn to be warped upon a beam or the like, said Creel comprising a semi-cylindrical casing, cop spindles arrangedL on the inner tace thereof, the axes ot the spindles coinciding with radii of the halt cylinder, and a comb situated at the rentre oi ythe half cylinder through which all the yarns Jfrom the cops or the like must pass to the warping trame.

ln a creel having the features claimed in claim l., yarn guides situated near the ends oiV the cops or the like to guide the yarn to the comb and prevent ballooning whilst allowing the yarn being unwound from the cops or the like to pass parallel to radii oi the halt' cylinder forming the creel.

il. il creci as claimed in claim l, having theedge oi" the casing nearer to the warping :trame lower than the halt cylinder axis, 'for the purpose set forth.

ln testimony whereof l aiiix my signature, in presence ot two witnesses.
